Once you got her attention be ready to engage her in something, if you can. If she can get away from the desk ask her to show you piece of a equipment or something like that.

Supermarket opener:

I was at the supermarket and saw this HB7.5 We both got to the store at about the same time. I made eye contact with her in a couple of different places, then, in one of the aisles I approached her and said

"I need your opinion. I've seen this girl in the store a few times, she's kind of cute and she smiled at me, my question is, were in a supermarket, are women really open to starting a conversation in a supermarket?"

She smiled and said, "Yeah, it's kind of something in the back of our minds when we show up here"

"Really? So I should just say hi and introduce myself to her?"

"yeah, that's usually all it takes"

"Cool, thanks" and I walk off. She looked a little confused. Two aisles over, I see her again, make eye contact, she smiles, I smile, and I approach. She starts to giggle as I walk up to her holding eye contact

"Hi, I'm strimpboi. I got some great advice to just come up and introduce myself to you"
